MDC – Future-proof modular system

MDC, short for Modular Design Construction, is NAD’s measure against hi-fi systems that are becoming obsolete too quickly. In particular, the technologies for A/V equipment are developing faster and faster in the last decades. As a result, home cinema who want to take advantage of new file formats, higher bandwidth High Speed HDMI connections, or additional height channels for surround playback like Dolby Atmos® are forced to replace their A/V receiver or amplifier on a regular basis. NAD’s MDC principle is to integrate all age-sensitive technologies on a high-quality plug-in card that can be quickly and easily exchanged for a newer version by a qualified technician. In addition, the MDC modules allow individual assembly of the corresponding NAD amplifiers.
